小巧玲珑百媚生

近几年来,为了全面考查初中学生的写作能力, 引导中学作文教学健康发展,不少省市已开始采用“一大一小”两道作文题进行考查。小作文主要考查学生的单项写作能力,常见形式为短小的议论文、描写或记叙片断、图画说明、修改作文和应用文考查等。俗话说,长文好做,短文难成。小作文虽“小”,但也“五脏俱全”,而且小作文还受篇幅和字数以及其他要求的限制,要想在考场上取胜,不掌握一些技巧是不行的。

Teaching Classic Probability Problems with Modern Digital Tools

This article is written to share teaching ideas about using commonly available computer applications—a spreadsheet, The Geometer's Sketchpad, and Wolfram Alpha—to explore three classic and historically significant problems from the probability theory. These ideas stem from the authors’ work with prospective economists, mathematicians, and teachers. The historical contexts include the problem of the division of stakes (14^th century), the problem of the Grand Duke of Tuscany (17^th century), and the problem of co-primality of two natural numbers chosen at random (19^th century). The suggested use of computers can be extended to other probability contexts to achieve at least two goals: to make complex mathematical ideas more accessible and to emphasize the importance of experimental evidence as a means of conceptual development in mathematics for all student populations.

Tools to make C programs safe： a deeper study

The C programming language is expressive and flexible, but not safe; as its expressive power and flexibility are obtained through unsafe language features, and improper use of these features can lead to program bugs whose causes are hard to identify. Since C is widely used, and it is impractical to rewrite all existing C programs in safe languages, so ways must be found to make C programs safe. This paper deals with the unsafe features of C and presents a survey on existing solutions to m…     

Improving caregivers’ confidence with the Powerful Tools for Caregivers program

ABSTRACT

The Powerful Tools for Caregivers (PTC) program is designed to help caregivers develop skills to improve their self-efficacy in caregiving. To demonstrate the effectiveness of the PTC program in Boise, Idaho, the program’s pre-survey (n = 277), end-of-program survey (n = 131), and 6-month follow-up post-survey data (n = 100) collected between 2011 and 2017 were analyzed in this study. The end-of-program survey data indicated that caregivers viewed the quality of the program to be excellent and that all of them felt more confident as a caregiver. Factor analysis and reliability testing on the pre-survey data confirmed that seven questions included in the pre- and 6-month follow-up post-survey instruments reliably measured a single factor named as caregiver confidence. A paired samples t-test on 76 complete sets of pre- and 6-month follow-up post-survey data on the seven questions revealed that caregivers improved their confidence in caregiving to a statistically significant level (p < .001, d = 45). Additional paired samples t-tests on each of the seven questions with the Bonferroni correction showed statistically significant improvements in three areas: making tough decisions (p < .001, d = .53), coping with emotions (p < .001, d = .54), and using stress-reducing activities (p < .007, d = .33). Caregivers experienced the greatest improvement in their confidence in making tough decisions. Despite these significant improvements, caregivers still struggled with finding ways to reduce stress and manage their emotions associated with caregiving as shown by the lowest pre- and 6-month follow-up post-survey scores. In addition to the study results, several considerations when synthesizing PTC research results are discussed.

Can Tracing Tools Contribute to Programming Proficiency? The LISP Evaluation Modeler

Abstract

Tracing solutions to programming problems is a long‐standing technique used to reveal the details of a solution and to expose bugs in a program. Tracing can also help programmers build a model or representation of how a programming language responds to code. This article describes the LISP Evaluation Modeler (LEM), an on‐line tracing tool designed to (a) help novices form an understanding of and facility with the LISP evaluation process, and (b) assist all programmers in designing and debugging programs. An empirical study of LEM demonstrates its advantages for design, comprehension, and debugging and suggests ways in which LEM can help novices learning LISP.

Faculty Evaluations: Contentious Bothers or Important Tools for Faculty Growth?

ABSTRACT

Over the years, there has been an increased call for accountability by legislators, policy makers, and the public for educators at all levels (Arreola, 2007; Fincher, 1983). College and university professors have not traditionally been subjected to much oversight or evaluation, especially after they receive tenure. Nevertheless, there are many models for tenure and posttenure evaluation (Arreola; Buller, 2012; Licata, 1986; Licata & Morreale, 1999). Each model emphasizes a variety of purposes such as encouraging faculty’s development as educators, as scholars, and as members of college communities. Other reasons include making recommendations for retention and/or tenure, evaluating teaching effectiveness, and evaluating overall performance. Provided here is an analysis of administrators’ and faculty members’ differing perceptions of faculty evaluations as well as suggestions for improving faculty performance reviews and implications for further study of faculty evaluation.
